Microspectroscopic investigations to determine surface contamination on chemically complex background matices in food safety

Doctoral project at a glance

Raw meat quickly shows bacterial infestation. If the infected meat is consumed, it can be a health hazard above a certain amount. Daniel Klein therefore wants to make contaminations (e.g. bacteria) visible on complex surfaces (e.g. meat). He combines spectroscopic data from IR and Raman spectroscopy from the same measuring regions to show where contaminations can be found. The combination of the two methods should increase the information content of the data set and at the same time reduce the error rate in contamination detection.
